Comparing The Carbon Budgets Of Boreal And Temperate Deciduous Forest Stands
Barr, A. G., Griffis, T. J., Black, T. A., Lee, X., Staebler, R. M., Fuentes, J. D., Chen, Z., Morgenstern, K.

Boreal and temperate deciduous forests at northern mid-latitudes play an important role in the global carbon cycle. We analyze 3 years (1996-1998) of eddy-covariance carbon dioxide flux measurements from two contrasting deciduous forest ecosystems in the boreal and temperate regions of central Canada. The two forest stands have similar …

Long-Term Observation Of The Atmospheric Exchange Of CO2 With A Temperate Deciduous Forest In Southern Ontario, Canada
Lee, X., Fuentes, J. D., Staebler, R. M., Neumann, H. H.

This paper reports the results of the analysis of eddy covariance CO2 data obtained at a successional forest of maple and aspen at Camp Borden in southern Ontario, Canada, between July 1995 and December 1997. Main findings are (1) The Michaelis-Menton model explains >50–65% of the observed variance of the daytime …

On The Seasonality Of Isoprene Emissions From A Mixed Temperate Forest
Fuentes, J. D., Wang, D.

Measurements of isoprene concentration and flux were made at a mixed deciduous forest in southern Canada during 1995 to characterize diel and seasonal emissions and thus deduce annual inventories. Isoprene …

Chemical Processing Of Biogenic Hydrocarbons Within And Above A Temperate Deciduous Forest
Makar, P. A., Fuentes, J. D., Wang, D., Staebler, R. M., Wiebe, H. A.

A one-dimensional canopy model was developed to study photochemical processes inside and above a mixed deciduous forest in southern Ontario. The Eulerian model made use of Lagrangian dispersion principles …

Responses Of Net Ecosystem Exchanges Of Carbon Dioxide To Changes In Cloudiness: Results From Two North American Deciduous Forests
Gu, L., Fuentes, J. D., Shugart, H. H., Staebler, R. M., Black, T. A.

We analyzed half-hourly tower-based flux measurements of carbon dioxide (CO2) from a boreal aspen forest and a temperate mixed deciduous forest in Canada to examine the influences of clouds on forest carbon uptake. We showed that the presence of clouds consistently and significantly increased the net ecosystem exchanges …

Climatology Of Gravity Waves In A Forest
Lee, X., Barr, A. G.

The objectives of this study are to establish a climatology of gravity waves in a forest and to gain insights into the dynamics of this motion type. The site is part of the BOREAS (Boreal Ecosystem—Atmosphere Study) flux monitoring network. The analysis relies mainly on 5 Hz temperature time series observed with two arrays of fine-wire …

Carbon Dioxide Exchange And Nocturnal Processes Over A Mixed Deciduous Forest
Lee, X., Black, T., den Hartog, G., Neumann, H. H., Nesic, Z., Olejnik, J.

This paper reports the results of the analysis of CO2 exchange from a one-month experiment conducted at a mixed deciduous forest, Camp Borden (80°65′W, 44°19′ N), Canada, in the summer of 1993. The mid-day CO2 flux from the forest under clear sky conditions was around −1.0 mg m−2

Ozone Deposition Onto A Deciduous Forest During Dry And Wet Conditions
Fuentes, J., Gillespie, T., den Hartog, G., Neumann, H.

Results of an experiment conducted to quantify the ozone deposition onto a deciduous forest stand in an acid-precipitation-impacted area of Canada are presented and discussed. The ozone deposition data were obtained above and within the forest canopy. The deposition process …
